Texas Sen. John Cornyn fell in line behind other top Republicans Wednesday and endorsed Mitt Romney for the Republican nominee.

The Republican senator has delayed giving his endorsement in the GOP race. But on Tuesday, House Speaker John Boehner and Senate Minority Leader Mitch McConnell separately offered their endorsements of Romney. McConnell noted that, as Romney is the likely nominee, it was time for the party to coalesce behind him.

Cornyn downplayed the endorsement Wednesday, but stressed the need for the party to unify behind a single candidate.

“The Republican primary is over. Mitt Romney will be our nominee and I will strongly support him in every way that I can,” Cornyn said. “But I think endorsements, frankly, are kinda overrated, so I don’t think its going to affect the outcome of the election.”
